Why didn't anyone remind me the dual booting exists?

I was talking to my dad yesterday and he talked about how he dual booted windows and Linux in his college days. I immediately left to download Ubuntu, I feel so dumb for forgetting it's an option. I literally only use windows so I can play Fortnite with friends. PSA: you can have both Linux and Windows, or you can use a vm in Linux. Be (mostly) free from Microsoft's clammy hands.
